The numbers of each given type of gas are present in 1.0 L of air at STP has to be calculated. Concept Introduction: STP in chemistry is the short form for Standard Temperature and Pressure . STP most usually is used when performing arts calculations on gases, such as gas density. The normal temperature is 273 K ( 0° Celsius or 32° Fahrenheit ) and the standard pressure is 1 atm pressure. This is the freezing point of pure water at sea level atmospheric pressure. A molecule is the minimum particle in a chemical compound that has the chemical properties of that compound. Molecules are made up of atoms that are held together by chemical bonds. These bonds form as a result of the sharing or exchange of electrons among atoms.

Show that a molecule with configuration π4 has a cylindrically symmetric electron distribution. Hint: Let the π orbitals be equal to xf and yf, where f is a function that depends only on the distance from the internuclear axis.

(a) Verify that the lattice energies of the alkali metal iodides are inversely proportional to the distances between the ions in MI (M = alkali metal) by plotting the lattice energies given below against the internuclear distances dMI. Is the correlation good? Would a better fit be obtained by plotting the lattice energies as a function of (1 — d*/d)/d, as theoretically suggested, with d* = 34.5 pm? You must use a standard graphing program to plot the graph. It generates an equation for the line and calculates a correlation coefficient. (b) From the graph obtained in (a), estimate the lattice energy of silver iodide. (c) Compare the results of (b) with the experimental value of 886 kJ/mol. If they do not agree, explain the deviation.
